ELNEC s. r. o.
Technical specification
HARDWARE
Base unit, DACs
• FPGA based IEEE 1284 slave printer port, up to 1MB/s
transfer rate
• on-board powerful microprocessor (20MHz) supported by
FPGA based state machine, 20MHz powered
• three D/A converters for VCCP, VPP1, and VPP2,
controllable rise and fall time
• VCCP range 0..8V/1A
• VPP1, VPP2 range 0..26V/1A
• autocalibration
• selftest capability
• protection against surge and ESD on power supply input,
parallel port connection
• banana jack for ESD wrist straps
Socket, pindriver
• pindrivers: 48 as standard, max. 256
• 1x VCC, 2x VPP can be connected to each pin
• perfect ground for each pin
• FPGA based TTL driver provides H, L, CLK, pull-up, pull-
down on all pindriver pins
• analog pindriver output level selectable from 1.8 V up to 26V
• current limitation, overcurrent shutdown, power failure
shutdown
• ESD protection on each pin of socket (IEC1000-4-2: 15kV air,
8kV contact)
• continuity test: each pin is tested before every programming
operation
Socket, base configuration
• 48-pin DIL ZIF (Zero Insertion Force) socket accepts both
300/600 mil devices up to 48-pin
